Condenser for refrigerator

Abstract

A condenser for refrigerator includes left and right or upper and lower headers spaced apart from each other for introduction or discharge of refrigerant, a tube unit including tubes mounted between the headers and spaced apart from one another to allow the refrigerant to pass through the tubes, and a fin structure mounted in the respective neighboring tubes to perform heat exchange between the refrigerant passing through the tubes and outside air, the fin structure including fins having a greater width than a width of the tubes. Providing the fins with a greater width than that of the tubes may achieve an expanded heat exchange range and higher heat exchange efficiency. Moreover, wider gaps between the fins ensure smooth air movement, causing a reduced pressure difference of the moving air and neither dust nor debris is trapped between the fins, resulting in higher heat exchange efficiency.

What is claimed is: 
     
       1. A condenser for a refrigerator comprising:
 left and right or upper and lower headers spaced apart from each other; 
 a tube unit including tubes mounted between the headers and spaced apart from one another, the tubes serving to transfer refrigerant introduced or discharged through the headers; and 
 a fin structure mounted in between the tubes to perform heat exchange between the refrigerant transferred through the tubes and outside air, the fin structure including fins having a greater width than a width of the tubes, 
 wherein the tube unit and the fin structure respectively have a U-shaped form, 
 wherein the tube unit and the fin structure define an inner space and an outer space and a blowing fan is located in the inner space, 
 wherein the blowing fan serves to blow air to the tube unit and the fin structure, 
 wherein the fin structure is protruded from the end of the tubes to the outer space, 
 wherein the fin structure is not protruded from the other end of the tubes to the inner space, 
 wherein the protruded region of the fin structure guides the flow of the air generated by the blowing fan and passed through the space between the fin structure and the tubes, and 
 wherein the fin structure between the tubes is longitudinally corrugated and has a pitch within a range of 2 mm to 10 mm to prevent trapping of dust. 
 
     
     
       2. The condenser for the refrigerator according to  claim 1 , wherein the tube unit and the fin structure are supported by a plurality of support members located at a lower end of the tube unit, and the support members are disposed on a base panel. 
     
     
       3. The condenser for the refrigerator according to  claim 1 , wherein each of the tubes defines a plurality of transfer paths inside each of the tubes. 
     
     
       4. The condenser for the refrigerator according to  claim 1 , wherein the tubes of the tube unit and the fins of the fin structure are vertically and horizontally stacked one above another.
